This may be a stupid question, but since this is the first time I've ever traded in a phone I thought I'd ask it anyway. I have a mint iP 5 (cased from day 1) that I'd like to trade in towards the purchase of a new iP 6+. I didn't preorder and I'm assuming I'll have no luck on Friday just walking into a store to purchase it. However, whenever it comes time for me to try to get one, how does the trade-in process work? I have Apple stores here in town, as well as BB and VZW stores (my carrier) very close to me. Do I have to go to VZW? Could BB or Apple do the same thing as my carrier's store and do a trade in? I preordered the 5 on launch day and didn't trade anything in so this is all new to me. Thanks for the guidance. ETA: I'll actually be using the upgrade for another phone on my family plan and switching it over to my number. My kids have used my and wife's upgrades previously so now I'm using one of theirs. The good thing is I'll get to keep my unlimited data plan (at least I hope) since I currently have that on my iP 5. I just didn't know if using a different line to upgrade then immediately switching the phone to my line changes where/how I buy it.
